Since it is important to be in compliance with the CAN-SPAM Act of 2003, we have that ability to build your own suppression lists. To make this even more convenient, we also have a massive, preexisting list of emails, domains, and bad email addresses that have been suppressed already. So, you will not have to go through the trouble of trying to contact people that do not want to receive any email advertisements.
Furthermore, our hard bounce manager has compiled a list of bad email addresses. These usually consist of email addresses that do not actually exist. Having a global block list and hard bounce manager built in will save you valuable time and effort in successfully fulfilling your marketing campaign.
